Fig. 1 fNIRS probe placement design for PFC, M1, and SMA measurements.
fNIRS probe placement design for PFC, M1, and SMA measurements. (A) Schematic depicting the FLS box simulator where trainees perform the bimanual dexterity task. A continuous-wave spectrometer is used to measure functional brain activation via raw fNIRS signals in real time. (B) Optode positions for coverage over the PFC, M1, and SMA. Red dots indicate infrared sources, blue dots indicate long separation detectors, and light blue dots indicate short separation detectors. The PFC has three sources (1 to 3), three short separation detectors (S1 to S3), and four long separation detectors (1 to 4). The M1 has 4 sources (4 to 7), 4 short separation detectors (S4 to S7), and 10 long detectors (5 to 14). The SMA has one source (8), one short separation detector (S8), and three long separation detectors (9, 15, and 16). Illustration by Nicolás Fernández. Arun Nemani et al.
